1. In a skillet, add the butter over medium heat. Place the onions in the pan and stir-fry until translucent. Add the garlic, sausage-style seitan, bell pepper, and mushrooms. Cook until tender.
2. Add in the flour. The vegetables should look like a flour-y crumbled mess. This is good right now! Next, add in the milk.
3. Add in all the spices and mix well. The gravy should be relatively thick, but not too much so. It also should not be thin like dressing. If too thin, add a little more flour in a bowl, add milk, mix well, then put it in the gravy. If too thick, add more milk.
